tion of the frame member.

Another object is to cheapen the frame member by eliminating the bracketor arm used in previous structures for facilitating mounting of thefourth point support or safety guard.

These objects and others are attained by the structures illustrateddrawings, in which in the accompanyin Figures 1 to 3, 5 to 8, 10, 11,13, 14, and 16 are vertical transverse sections through truck sideframes illustrating various forms of the invention applied thereto.

Figure 4 is a view in perspective of a detail of the form in Figure 3.

Figure 9 is a side view of the structure shown in Figure 8.

Figure 12 is a detail section taken substantially on the line l2l2 ofFigure 11.

Figure 15 is a horizontal section through a truck side frame andillustrates another form of the invention.

In each of the figures, except Figure 16, the invention is illustratedas applied tothe lower chord of a truck side frame casting of familiarconstruction, only the part of the frame to which the guard, guide orsupport bracket is attached being illustrated.

The frame includes a bolster spring seat I having a hollow box sectionportion beneath the same including side walls 2 and 3 and a bottom wall4, see Fig. 1. Side walls 2 and 3 are provided with alined perforationswhich receive elongated boltlike portion 5 at the outer end of asidewardly ex tending arm 6 on the bracket I which mounts the brake beamguard, guide or support member 8 by means of pin 9. The bolt-likeportion 5 is threaded for nuts Hi and I I which engage the outersurfaces of walls 2 and 3 and maintain the bracket 1 and the guard,guide or support device in the proper position on the side frame.

In Figure 2, the spaced side walls l2 and i3 beneath the bolster springseat H! are perforated at l5 and I6 for receiving the outer portion llof the sidewardly extending arm is on the guard,

Portion I! at its outer extremity includes depending legs 20, the outerextending along the outer surface of wall !2 and the inner extendingthrough a perforation 2! in the bottom wall 23 of the side frame. Legs23 receive pin 22, which abuts the bottom wall, 5 for maintaining thebracket in position. Perforations [5 and 16 are elongated transverselyof arm l8 to permit the insertion or removal of legs 20 when the arm isturned ninety degrees from the position shown. An enlargement 24 is pro-10 vided for abutting the inner surface of the wall In Figure 3, thesidewardly extending arm 25 on the guard, guide or support bracketextends through perforations 26 and 2'! in the side walls 15 of theframe member and has a. lug 28 and a hooked end 29 abutting the outersurfaces of the side walls. A U-shaped clip 30 rests upon a portion ofarm 25 between the frame walls and the legs thereof depend throughsuitable perforations in the bottom wall 3| and receive a holding pin32.

Perforations 2B and 21 and the'hooked end 29 are shaped similarly toperforations l5 and i6 and legs 2!, respectively, in Figure 2 toaccommodate insertion and removal of the bracket upon rotation of thebracket ninety degrees from the position shown.

In Figure 5, perforations 40 in the spaced side frame walls are providedwith sidewardly extending perforated lugs 41 which receive pins 42 forsecuring the bracket arm 43 in position. A finger 44 depends from theportion of arm 43 inwardly of the side frame and curves beneath andabuts the bottom wall 45 of the frame. This 35 finger serves to relievethe arm 43 of bending forces caused by the weight of the guard, guide orsupport bracket.

In Figure 6, the bracket arm 33 extends through perforations 34 in theside walls of the frame member and has a hook 35 at the outer endengaging the outer side wall and has a depression 36 between the wallswhich receives a pin 31 mounted in a bracket 38 projecting from thebottom wall 4 39 of the frame. 5 r

In Figure '7, the bracket arm 46 is held in position by means of anenlargement 41 abutting the inner side wall 48 and a pin or key 49secured between bifurcations 50 at the outer end of the arm by a cotter5|. 50

The bracket arm in Figure 8 is similar to that in Figure 7 except thatan enlargement 52 is formed integral with the bracket arm 53 at theouter extremity and the perforations 54 in the spaced side walls of theframe member are made 55 large enough to receive the enlargement 52 whenthe bracket 55 is turned on its side, in the manner illustrated inFigure 9. Enlargements 52 and 56 abut the side walls of the frame, whenin normal position, to hold the bracket in place.

In Figure 10, the bracket arm 51 is shown as extending through the innerwall 58 only of the side frame andenlargements 59 and 60 abut thesurfaces of the wall for preventing tilting of the bracket. The bracketis turned 90 degrees, as in Figure 9, to permit insertion of theenlargement .60

through the perforation 61.

In Figures 11 and 12, the bracket arm ,62 has enlargements 63 and 64 forholding the bracket in position, and a bent flat spring 65 is applied tothe arm inside the hollow side frame. Spring 65 engages the undersurface of the bolster spring seat 66, and by forcing arm 62 against thelower edges of perforations in the spaced walls of the side frame,prevents rattling of the bracket.

Enlargement 64 is elongated vertically and the openings in the sideframe are elongated hori zontally to permit passage therethrough ofenlargement 64 when the bracket is rotated ninety degrees from theposition shown, corresponding to the showing in Figures 8 and 9.

In Figures 13 and 14, other means of preventing rattling areillustrated. Figure 13 shows a spring 61 applied to the outer end of thearm 68 and compressed between the outer frame wall 69 and a washer 61aforming an abutment for the outer end of the spring and held in place bya key 61b. Enlargements I abutting the inner frame wall H limit themovement of the bracket arm. The inner enlargement corresponds in shapeto the similar element 52 in Figure 8, and the opening in the left handportion of the side frame is elongated, as opening 54 in Figure 9, topermit insertion and removal of the bracket arm. In Figure 14 the'innerenlargement 12 is spaced from a the inner wall 130i the side frame and acoiled spring 14 is compressed between enlargement l2 and the innerwall. The outer enlargement is passed through the openings in the sideframe in the manner previously described for similar elementsin Figures8, 11, and 13.

Figure 1 5 shows a one-piece strap-like member including inner portionsfor association with the brake beams and an outwardly offsetintermediate portion 16 which abuts the wall 11 of the side frame. Thestrap is secured to the frame by means of a bracket device includingbolts 18 extending through spaced walls 1! and 19, plates 80 being"provided to strengthen the connection.

In Figure '16, the guard, guide or support member 81 is shown carriedfrom above by means of a bar 82 which extends through the portion 83 ofthe side frame above the bolster opening 64 and is secured in place by apin or key 85. The bar .82 may abut the hanger bracket 86, and alug 61,shown dotted, provided to stabilize the guard or support. In this case,a wall of member t8 and the inner surface of bracket 86 constitutespaced parts of the truck side frame balancing the guard, guide orsupport bar 82.

In each of the forms, the guard, guide or support bracket is attached toa frame part without the provision of any rigid inwardly extendingbracket or arm which would increase the cost of the truck frame and beliable to breakage. Moreover, in each of the forms, except that inFigure 10, the weight of the bracket is distributed betweensubstantially spaced walls, the inner wall receiving downward pressureand the outer wall upward pressure due to the tendency of the bracket totilt about the inner wall as a pivot. In the form shown in Figure 10,the weight of the bracket is distributed over a substantial portion ofthe single supporting wall.

The use of the novel supportbracket is not limited to the type of sideframe illustrated, and in fact the attachment of a guard, guide orsupport device to another truck structural part, such as a transom orspring plank, would be facilitated by utilization of the novel featuresof the invention. The particular point of attachment of the bracketto'its supporting member is not essential.

,Any form of guard, guide or support member may be used and a resilientstrap member may be provided-for engaging a chair depending from thebeam, .or the device may be spaced beneath the beam serving only as asafety guard, or the beam maybe suspended from above in the mannerillustrated in my co-pending application Serial No. 550,238, filed July11, 1931.
